Abstract – The effect of sucrose and mineral salts on morphogenesis of the Catherine’s moss (Atrichum undulatum) in in vitro culture was tested. In vitro culture of this species was established from disinfected spores on Murashige and Skoog (MS) medium. Apical shoots of gametophytes were used to investigate the influence of sucrose and mineral salts on protonemal and gametophyte growth and multiplication. Paper also treats morpho-anatomical characteristics of plants grown in nature and plants derived from in vitro culture.
